Often desired, but rarely found in the wood stove industry: the fast heat, for which wood stoves are known and liked for, should also be combined with long-lasting heat storage. Austroflamm’s Heat Memory System makes impossible 9 hours of heat emission possible (and it still remains a fast heating system)! The progressive development of the approved Austroflamm Heat Memory System probably offers the best heat storing: we combine the Heat Memory System with a special heat exchanger, stow more than 100 kg of it into a wood stove and additionally equip the stove with an adjustable convection air which can even be shut off. More than 12 hours of heat release with less than 9 kilos of wood.
